-=head2 Init(flags)
-
-As with the C language API, SDL_perl initializes the SDL environment through
-the C<SDL::Init> subroutine. This routine takes a mode flag constructed through
-the bitwise OR product of the following functions:
-
-=over 4
-
-=item *
-INIT_AUDIO()
-
-=item *
-INIT_VIDEO()
-
-=item *
-INIT_CDROM()
-
-=item *
-INIT_EVERYTHING()
-
-=item *
-INIT_NOPARACHUTE()
-
-=item *
-INIT_JOYSTICK()
-
-=item *
-INIT_TIMER()
-
-=back
-
-C<SDL::Init> returns 0 on success, or -1 on error.
-
-=head2 GetError()
-
-The last error message set by the SDL library can be retrieved using the subroutine
-C<SDL::GetError>, which returns a scalar containing the text of the message if any.
-
-=head2 Delay(ms)
-
-This subroutine allows an application to delay further operations for atleast a
-number of milliseconds provided as the argument. The actual delay may be longer
-than the specified depending on the underlying OS.
-
-=head2 GetTicks()
-
-An application may retrieve the number of milliseconds expired since the initilization
-of the application through this subroutine. This value resets rougly ever 49 days.
-
-=head2 AddTimer(interval,callback,param)
-
-C<AddTimer> will register a SDL_NewTimerCallback function to be executed after
-C<interval> milliseconds, with parameter C<param>. SDL_NewTimerCallback objects
-can be constructed with the C<NewTimer> subroutine. C<SDL::PerlTimerCallback>
-will return a valid callback for executing a perl subroutine or closure.
-This subroutine returns a SDL_TimerID for the newly registered callback, or NULL
-on error.
-
-=head2 NewTimer(interval,subroutine)
-
-The C<NewTimer> takes an interval in milliseconds and a reference to a subroutine
-to call at that interval. The subroutine will be invoked in a void context
-and accepts no parameters. The callback used is that returned by C<SDL::PerlTimerCallback>.
-C<NewTimer> returns the SDL_TimerID for the new timer or NULL on error.
-
-=head2 RemoveTimer(id)
-
-This subroutine taks a SDL_TimerID and removes it from the list of active callbacks.
-RemoveTimer returns false on failure.

-=head2 SetTimer
+=head2 Documentation
-This subroutine is depreciated, please use C<NewTimer> or C<AddTimer> instead.

-=head2 CDNumDrives()
+=head2 Perl Development
-C<SDL::CDNumDrives> returns the number of available CD-ROM drives in the system.
-
-=head2 CDName(drive)
-
-The subroutine C<SDL::CDName> returns the system specific human readable device name
-for the given CD-ROM drive.
-
-=head2 CDOpen(drive)
-
-This subroutine opens a CD-ROM drive for access, returning NULL if the drive is busy
-or otherwise unavailable. On success this subroutine returns a handle to the CD-ROM
-drive.
-
-=head2 CDTrackListing(cd)
-
-C<SDL::CDTrackListing> returns a human readable description of a CD-ROM. For each
-track one line will be produced with the following format:
+ Nick: Garu
+ Name: Breno G. de Oliveira
+
+ Nick: Dngor
+ Name: Rocco Caputo
- Track index: %d, id %d, %2d.%2d
+ Nick: nferraz
+ Name: Nelson Ferraz
-This is provided to ease the creation of human readable descriptions and debugging.

-=head2 CDTrackLength(track)
+First set the PERL5LIB environment variable to the dependencies of your script
+
+ %export PERL5LIB=$PERL5LIB:./lib
-C<CDTrackLength> returns the length field of the given SDL_CDtrack structure.
+Use the SDLPerl executable made in the bundle and call your scripts
-=head2 CDTrackOffset(track)
+ %SDLPerl.app/Contents/MacOS/SDLPerl yourScript.pl
-C<CDTrackOffset> returns the offset field of the given SDL_CDtrack structure.
